Title: Method for controlling supply quantity of granular substance
Inventor: MIYAGAWA TERUYUKI
IPC: G01F13/00
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To secure setting supply quantity by adopting pressure change inside a pneumatic carrier as a main signal so as to operate the supply speed of volume feeder and indirectly controlling the supply quantity of granular substance. SOLUTION: After the end of the reception of granular substance to a service hopper 4, appearance bulk specific gravity is obtained by volume and weight which are measured by a level measuring instrument 12 and a weight measuring instrument (load cell) 14. The bulk specific gravity is adopted as the one in previously set supply quantity (flow rate set value) so as to be adopted in a transport tube (pneumatic carrier) pressure operation and control setting pressure is calculated by set supply quantity. The supply speed of the volume feeder 10 from the discharging port of the feeder 10 provided in a measuring hopper 8 is operated with internal pressure change which is measured by a pressure meter (flow rate measurement) 13 positioned at the downstream side of the pneumatic carrier 11 as the main signal. Then, the supply quantity of granular substance is indirectly controlled.

Title: Multistage amplifying light-transmitting system and optical amplifier
Inventor: NAKAZATO KOJI
IPC: H04B10/255
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To provide a multistage amplifying light-transmitting system which can maintain good transmission property, such as SN ratio and waveform distortion. SOLUTION: Signal light output from a transmitter 100 is amplified through optical amplifiers 3101 to 310N for each stage one by one.

Abstract: PURPOSE: To enhance the compression restorability, flexibility and strength of graphite without losing the characteristics by treating the graphite with a soln. prepared by dissolving a specified amt. of potassium permanganate in conc. sulfuric acid, followed by washing, heat expansion and heat molding.  
     CONSTITUTION: 100pts.wt. of graphite such as natural flake graphite is treated for 0.5W15hr in a soln. prepared by dissolving 7W25 parts of potassium permanganate in about 500 parts of conc. sulfuric acid. The treated graphite is then charged into a large amt. of water together with the soln. to filter and wash the graphite. The washed graphite is optionally treated with phosphoric acid or the like to control oxidation and heat expanded at about 600W800°C for 1W3min to obtain graphite particles expanded to a bulk density of about 0.005W0.02g/cm 3 . The particles are press-molded by compression molding or other method. Thus, a flexiblie graphite material suitable for a gasket and packings is produced.

Title: On-line method for measuring coated-film thickness
Inventor: KURITA KOICHI
IPC: G01B17/02
Filed: 1994-07-08
Abstract: PURPOSE:To measure film thickness accurately on-line over the whole length by using an ultrasonic sensor for measuring distances up to a steel plate not coated and up to the surface of a coated film after the drying of coating and obtaining the difference of the measured distances. CONSTITUTION:A coil steel plate 1 is coated by a coater 2, and a coated film is dried and baked 3, and cooled in a water tank 4. The distance up to the coated steel plate 1 supported by a roller 5 is measured by an ultrasonic sensor 6. The thickness of the coated film is acquired by the difference of the value and distance up to a steel plate not coated previously measured in the same arrangement. The temperature change of water between the sensor 6 and the steel plate 1 largely has effect on the accuracy of measurement at that time. Consequently, water set at a fixed temperature by a temperature regulator 7 is ejected as a water jet from a nozzle 8, and an ultrasonic propagation path is measured while being kept at a fixed temperature. Accordingly, film thickness can be measured accurately without generating a large error. The signal of the sensor 6 is input to a film-thickness measuring device 10 through a distance display unit 9, and displayed as a film thickness value.

Filed: 1978-12-22
Abstract: PURPOSE: To better a thermal absorption factor and to obtain stable gas feed in a small quantity by feeding white kerosene into a vaporizing pipe in a fog-like shape.  
     CONSTITUTION: White kerosene is atomized into a vaporizing pipe 1 while natural gas, etc. are supplied to by-nozzles 8, the vaporizing pipe 1 is heated, a gas injection port 2 is opened by means of a handle 3 when the pipe reaches a fixed temperature, and white kerosene gas evaporated by the heat of the natural gas is fed to a flame pan 7. After the white kerosene gas is brought to a condition that can be supplied, the white kerosene gas evaporated at the vaporizing pipe 1 is fed to the by-nozzles 8 in place of the natural gas, etc., and the vaporizing pipe 1 is heated by means of the nozzles 8. In this case, the white kerosene is continuously atomized into the vaporizing pipe 1 by means of a spray nozzle 4, and the white kerosene atomized is instantaneously evaporated in the vaporizing pipe 1. Thus, the surface area of the white kerosene remarkably becomes larger, a thermal absorption factor is improved and the white kerosene is rapidly evaporated because the white kerosene is supplied under a condition that is atomized.

Title: Bulb for color cathode-ray tube
Inventor: HOSOYA NOBUHIKO
IPC: H01J29/86
Filed: 1990-06-18
Abstract: PURPOSE:To prevent neck shadow from being easily generated by introducing such a constitution that the spacing between the inner surface of a funnel and the locus of an electron beam emitted from the sideways located one of the three electron guns arranged in a plane becomes long. CONSTITUTION:The funnel of a CRT glass bulb is composed of a neck 3, cone 1, and a cone 2 for mounting a deflection yoke on the outside. A groove (fluit) 4 is provided in the inner surface of the yoke part 2 bending with convex up the funnel on the glass surface likely to give cause of neck shadow while intercepting electron beam. In the projective diagram on a plane perpendicularly intersecting the tube axis on the inner surface of the funnel, the fluit 4 is not projected on a straight line tying the central electron gun 6 to the four corners of the display screen, but is so formed to be projected on the straight line tying the sideways located electron gun 7 with two corners on the same side as the applicable electron gun on the display screen. Thereby the spacing between the wall surface of the funnel and the locus of electron beam being deflected from the sideways electron gun toward the corner of the display screen can be made 0.5-0.8mm longer than conventional, and thus neck shadow is hard to be generated accordingly.
